Protocatechuic acid CAS 99-50-3 Protocatechuic acid (PCA) waa 3,4-dihydroxybenzoic acid. Waa aashitada phenolic fudud, oo horudhac u ah isku dhafka molecules kale ee kakan, sida anthocyanin 3-ochemicalbook- β- D-glucoside iyo vanillin. Waxaa laga helaa khudaarta la cuni karo, miraha, lawska, bariiska bunni, pecans, shaaha, ubaxa hibiscus iyo qaar ka mid ah dawooyinka dhirta Shiinaha.
